you can always disconnect the battery to erase the cel.

i have no cel, but i just disconnect the battery and reconnected it and went for a spin and this is whats happining. when i give it gasthe boost goes to 10 psi, sputters for a second then it boost higher, do u think i just need to drive it more to let computer adjust

yea im pretty sure its not limp mode, i have no cel either. the car runs fine untill u give it gas enough to make it go to 10 psi then it spudders and it feels like crap

does your cel ever flash? and does the car shudder kind of bad when its boosting 10psi??

yep kompressed you got it on the money. i changed out the denso plugs and put the old plugs back in(autozone didnt have replacement) and my problem is fixed. i need to still clear the codes and get new plugs
